Question

The circle below has center O, and its radius 4in. Given that m

Answer 1

In order to find the length of the arc, we can use the following formula:

`l=r\theta`

Where r is the radius and θ is the central angle in radians.

So first, let's convert the angle to radians:

`50\degree=50\cdot(\pi)/(180)=(5)/(18)\pi`

Now, calculating the length of the arc:

`\begin{gathered} l=r\cdot\theta \\ l=4\cdot(5)/(18)\pi \\ l=(10)/(9)\pi \end{gathered}`
